Good and bad
You have a lot going for you but you also have a lot to improve on.
Story aside, since I hate anything associated with High School Musical, the animation wasn't bad. It was mainly tweens, but you know how to tween and make it look good. The fight scene in particular was good.
The gripe I have with tweening though is that it's too simple. You had a lot of great tweens, but what would have made it cooler is if you put some frame by frame in your movie. It takes longer, but you can make much better stuff. Overall there is more freedom with it.
Something you need to work on big time is pacing. Throughout the movie, save for the fight, there were many unnecisary and long awkward pauses where a character would make a very long facial expression or just stare into the abyss. The audio looping made this even more noticable and made those parts feel extra long.
Aside from these things, this was a good movie. Work on pacing and some frame by frame and your next movie will be better than this.
Good job and good luck.
